I am now almost certain that we need more radiation for better health.

The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.

I have the satisfaction of knowing I did something useful for society.

Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.

When I entered the field in July 1958 I believed what they told me about radiation risks. I spent much effort reducing the dose to patients in radiology.

Medical physicists work in cooperation with doctors. A few medical physicists devote their time to research and teaching. A few get involved with administrative duties.

Too many radiologists still believe there is a risk from a chest x-ray. Few radiologists can explain radiation to the patient in words the patient can understand.

I am now almost certain that we need more radiation for better health.

I was the Chair of the first department of medical physics in a medical school in the U.S.

There are now over 5,000 medical physicists in the U.S more than 50 times the number in 1958.

Many Nobel Prizes are awaiting good research to understand and explain the many mysteries of our bodies, such as the basic mechanism of memory or imagination.

In 1970 I realized that there was negligible risk from x-rays but many radiographs had poor image quality so that the risk from a false negative was significant.

I would not encourage everyone to take up this profession. Not everyone is suited for any particular field.

We developed simple test tools to optimize imaging parameters. No company was interested in our idea.

If someone is interested in medicine and also in physics and they like working with people and communicate well with others, I would strongly encourage them.

I have devoted much time and energy to helping medical physics in developing countries.

I am sure that I have been much more useful to society as a medical physicist.

In some cases radiation reduces the incidence of cancer.

I am not unhappy that my contribution was not recognized. I am sure it helped my career.

I don't display my plaques and honors. They are hidden behind a black curtain in my work room at home.

Nuclear physics is interesting but it is unlikely to help society.

Medical physics is an applied area of physics.

I found collaborating with congenial doctors about problems that physicists could help solve was very satisfying. I also like educating anybody who would listen!

It is likely that we need more radiation to improve our longevity.

My main frustration is the fear of cancer from low dose radiation, even by radiologists.

I started the nuclear medicine laboratory at UW Hospitals in 1959 and trained radiology residents in the field. It was 1965 before they found a trained MD (doctor) to take over my role.

When I entered medical physics in 1958 there were fewer than 100 in the U.S. and I could see many opportunities to apply my knowledge of nuclear physics.

Even if you walk exactly the same route each time - as with a sonnet - the events along the route cannot be imagined to be the same from day to day, as the poet's health, sight, his anticipations, moods, fears, thoughts cannot be the same.

From dear, dear Gloria Swanson, I learned how to live long, happy and free of health problems. I owe her my life.

The greatest public health threat for many American women is the men they live with.

As patients and consumers, we are better informed today about our health care than any previous generation.

Happiness is nothing more than good health and a bad memory.

The surest way to return to the people's business is to listen to the people themselves: We need to drop this whole scheme of federally controlled health care, start over, and work together on real reforms at the state level that will contain costs and won't leave America trillions of dollars deeper in debt.

Health is the greatest gift, contentment the greatest wealth, faithfulness the best relationship.

On health care, virtually every political error that could be made was made.

Learning is the beginning of wealth. Learning is the beginning of health. Learning is the beginning of spirituality. Searching and learning is where the miracle process all begins.

Advances in science and medical research and public health policies have meant that life expectancy for Australians is one of the highest in the world.

Actually, I've been a fanatical health nut for five years.

Happiness, contentment, the health and growth of the soul, depend, as men have proved over and over again, upon some simple issue, some single turning of the soul.

I think health is another exceedingly important thing.

From this experience we have learned that in a big party it is important to have the necessary and often controversial discussions on policy issues such as the health system while in opposition.

A modern health and social care system has to be completely focussed on the needs of its users.

Health is the greatest possession. Contentment is the greatest treasure. Confidence is the greatest friend. Non-being is the greatest joy.

Any veteran can tell you it is already hard enough to see a doctor down at the VA and get the health care they were promised when they signed up to serve this country.

Obama's health care plan will be written by a committee whose head, John Conyers, says he doesn't understand it. It'll be passed by Congress that has not read it, signed by a president who smokes, funded by a Treasury chief who didn't pay his taxes, overseen by a Surgeon General who is obese, and financed by a country that's nearly broke. What could possibly go wrong?

Nothing is more capable of troubling our reason, and consuming our health, than secret notions of jealousy in solitude.

People who are always taking care of their health are like misers, who are hoarding a treasure which they have never spirit enough to enjoy.

The truth is, in order to get things like universal health care and a revamped education system, then someone is going to have to give up a piece of their pie so that someone else can have more.

If bringing up the next generation is important, why aren't they the best qualified, the best paid? Why aren't we as concerned about their career progression as we are about those who work in the education or health services?
